BMW may sell engines and transmissions to GM and Fiat

Word out of Frankfurt from the Financial Times Deutschland is that BMW is in talks to sell engines and transmissions to both General Motors and Fiat. All three companies have declined to officially comment.

The news is interesting, but not surprising. You may recall that GM has been selling transmissions to BMW for well over a decade for use in various 3 Series and 5 Series models (the current BMW 328i automatic uses a 6-speed GM 6L45 unit). So far, however, all have been automatic transmissions.

Speculating about the details, our tipster suggests that BMW may be helping GM with their SMG-style transmission program. As for the engines? It is possible that BMW could be selling its 4.4L V8 for the Cadillac line or lending GM a twin-turbo to compete with Ford\'s twin-turbo direct-injected V6? Thanks for the tip Brad



gm에 델파이가 있다는 것은 알고 있었지만 얘들이 bmw한테까지 십수년간 모듈 팔아먹고 있다는 것까진 나도 몰랐는데, 최근 알아버리고 말았어. GM 6L**시리즈라면 GM의 각종 저렴한 차종들에도 들어가는 자동변속기인데, 난 벌렁벌렁 놀란 가슴을 진정시키느라 기어코 죠지아 캔커피 하나를 사서 목을 축이고 겨우 정신을 차렸어... 다시 전열을 가다듬고 대체 이 GM제 변속기가 BMW 어디에 그렇게 쓰이는지 알아봤더니

 

The 6L50 (and similar 6L45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors. It is very similar in design to the larger 6L80/6L90, and is produced at the GM Powertrain plant in Strasbourg, France. The 6L50 will debut for the 2007 model year on the V8-powered versions of the Cadillac STS sedan and Cadillac SRX crossover, and will eventually replace the 5L40-E and 5L50 in GM\'s lineup. The 6L45 version is totally dedicated to BMW applications, either RWD or AWD.

The 6L50 is adaptable to rear-wheel drive and all-wheel drive applications. It can accommodate engines with up to 332 ft·lbf (450 N·m) of torque, and vehicles with a GVWR of 5,000 lb (2,268 kg).
